The Newport News Shipbuilding division of HII alongside General Dynamics Electric Boat (abbreviated GDEB) has recently sourced a unique component from a 3D printing firm dubbed AMMCON, which they’ll integrate onto the Virginia-class attack submarine, Oklahoma (SSN 802).
The two original equipment manufacturers (popular as OEM) of the Virginia class have focused on the availability and deployment of marine-based alloys, like copper-nickel, as an alternative to conventional copper-nickel castings.
